Analyzers based on the frontend can benefit from knowing the range of

This change reimplements from scratch the Ada.Task_Attributes package,
taking advantage of RM permission C.7.2(28), and putting a maximum number
of task attributes supported to simplify the implementation and make it
more efficient. In addition, a special ("Fast_Path") case is made for

This patch fixes several race conditions involving independent tasks.
The main thing is to make sure the activating task waits for them
to become independent. Otherwise (for example) the environment task
can race ahead to Finalize_Global_Tasks and find things in an
inconsistent state, causing progr
In GNATprove mode, some subprograms may be partially inlined, due to
recursion, or because some calls are in a potentially unevaluated context,
which would lead to code that GNATprove would not be able to handle. In
those cases, the body-to-inline has been built, and potentially already be
inlined.
